Research Abstract

In this work, micro fabrication techniques for waveguide components suitable for millimeter-wave and submillimeter-wave applications have been developed. The PTFE microstructures are fabricated by direct exposure to synchrotron radiation, and the waveguiding structure is obtained by sputter deposition of metal on the PTFE surface. In this work, an iris-coupled bandpass filter and a cruciform coupler with air-filled posts inclusive of bends and discontinuities were designed and fabricated, and the validity of the present fabrication process was demonstrated.
